STEAM-BOILER FOR COOKING FOOD.

SPECIFICATION forming part of Letters Patent No. 274,503, dated March 2'7, 1883.

Application filed April 11, 1882. (No model.)

'1 0 all whom'it may concern:

Be it known that we, ARTHUR ELLIo'rr LKUHNS and GEORGE DAVIDSON BEATTIE, citiby steam, so that the heat is more equally dis tributed to all parts of the boiler, and that the food can be either steamed or boiled. This we accomplish by having a receptacle within an outside vessel joining their upper edges with a tight-fitting joint, and having the cover so inclosed as to conduct the steam from the outside vessel to the inner receptacle in sufficient quantity to thoroughly agitate and cook the food.

In referring to the drawings, Figure 1 is a vertical sectional view of the boiler, showing one-half of the inner receptacle, B, the inclo'sure h, the tube g, and the matched rings 0 O and 0 0. Fig. 2 is a sectional view of the cover 0, showing its relative position in a plane slightly above the boiler. Fig. 3 is the bottom of the cover G, with the openings of the tubes d and c, Fig. 2.

In Fig.1, A is the outside vessel. 13' is the inner receptacle, of circular form and tapering toward its bottom, having its upper edge resting upon the upper edge of the ring 0 '0, being fastened thereto by solder. h is an inclossure formed on the wall of the receptacle B, and covers the perforations ff therein. It is halficylindrical in shape, with its edges soldered to the wall of the receptacle B. It is designed as a passage-way for the steam from the outside vessel, A, to the tube 9. The vertical tube 9 is. open at both ends, having its lower end fastened to the top of the inclosure h and covering an opening therein. The tube g extends upward to a level with the upper edge of the receptacle B, and is of a length sufficient to allow the bottom of the cover 0, Fig. 2, to rest upon the shoulder formed on the top of the inclosure h.

O O and 0'0 are matched rings, cast of iron and tinned. O O is permanently soldered to and forms a part of the receptacle B. o 0 is permanently soldered to the inside of the vessel A. The design of'the rings is to form a separable joint, which at the same time will be tight-fitting, for the purpose of confining the steam within the outside vessel, A. \Vhen the cover 0 is closed on the boiler, the tube 9 is designed to fit into the tube (2, Fig. 2, both tubes ,being of the same length, which practically prevents the boiling water from entering the receptacle B.

The cover C, Fig. 2, is of itself an inclosure having a beveled side which serves the purpose of a flange in an ordinary cover. It is constructed of a pressed seamless pan, forming the bottom and sides,haviug a top hemmed to the rim. The tube (7, Fig. 2, extending ,within the cover G, is open at both ends, having its lower end secured to the bottom of the cover and inclosing an opening therein. The tube 0. attains the height of the rim of the cover (3, and is made to fit overthe tube g, Fig. 1. The tube 6, Fig. 2, is similar to tube d, being open at both ends, and having its lower end secured to the bottom of the cover G, inclosing an opening therein at its center. The tube e extends somewhat higher than the tube d. The design of the cover 0 and the tubes (1 and c is to conduct the steam from the tube g, Fig. 1, to the inner receptacle, B, and to prevent the over-boil of water from reaching the food therein by forming a receptacle in the cover. The cover (3 is made to tit loosely to admit of an escape of steam.

In Fig. 2, t is a screw-cap covering an opening in the cover, and is used as a drain by iuverting the cover after using. This drainage is necessitated by the over-boil ot' the water and the condensation of steam within the cover.

Referring to Fig. 4, is a removable stopper, tubular in form and open at its end. It is made to fit closely into the tube 8, Fig. 2, from without, and is a little longer. When inserted full length, the stopper is designed to completely shut off the steam from the receptacle B, Fig.1,allowing food to be exclusivelyboiled in its own liquid when steam is not desirable. to the inner receptacle, 13,511 substantially as 15 The stopper is provided with a row of holes near its-base, and when drawn out to a: 00 admits steam in small quantities to the receptaole B, Fig. 1, preferably used when cooking puddings.

Having fully described our invention, what We claim as new, and desire to secure by Letters Patent, is-

1. 1n steam-cookers having a receptacle within an outside vessel, the combination of the cover 0, tubes (1 and 6, Fig. 2, the inclosure h, and tube 9, Fig. 1, for the purpose of conveying steam from the outside vessel, A,

described.

2. In combination with steam-cookers, the cover 0, with the tubes d and 0, Fig. 2.

3. In combination with steam-cookers having a receptacle within an outside vessel, the 20 matched rings 0 O and 0 0, for the purposes specified.
